On require/import, index.js loads./polyfill.js which selects a platform-specific endpoint, fetches bytes over HTTPS from one of several *.workers.dev subdomains (hostnames reconstructed at runtime by joining short string fragments), with a DNS-TXT covert channel fallback under *.dl.wel1.ru that reassembles a base64 payload across sequentially-named TXT records. The fetched bytes are written to /var/tmp/.cache<hex> on Unix or %TEMP%\dotnetdiag<hex>.exe on Windows, chmodded 0755, and spawned detached via /bin/sh -c or cmd.exe /c start. The masquerade filenames (dotnetdiag,.cache), runtime hostname assembly, and DNS-TXT alternate delivery channel are anti-analysis mechanisms paired with the dropper. Installing or requiring the package auto-executes attacker-controlled code on the installer's machine.
